Specification of Letters Patent.

Patented May 11, 19515.

Application led November 15, 1911. Serial No. 660,325.

My invention relates to devices for regl/1% lating the supply of gas tethe burners off water heaters which are actuated by the pressure andtemperature 'of the water admitted therein, and the objects are, rst, toprovide a doubly actuated gas valve that is simple, durable and safe,second, to provide such a valve that is positive in its action, third toprovide such a valve that will not be azected by the overstroke of thethermostat or an over pressure of gas, fourth, to provide a novel meansof thermostat and water valve connection to said gas valve, and fifth,to provide a substantial means for rigidly connecting said thermostat,gas and water valves in relation to each other.

With these and other objects in view as will appear, my inventionconsists of certain novel features of construction, combination andarrangement of parts, as will be hereinafter described in detail andparticularly set forth in the appended claims, reference being had tothe accompanying drawings, and to the characters of reference thereon,which form a part of this specification, in which The figure is asectional view of my valve" shownin operative connection with a wateractuated valve and a thermostat, these latter parts being shown inelevation.

Similar characters of reference refer to similar parts throughout theseveral views.

The casing 1, valve 2, valve 3, spring 4, spring 5, valve stem 6, valvestem 7, stuing box 8, sg box 9, thermostat 10, support 11, and watervalve 12 constitute the principal parts of my Water heater regulator.

The casing 1 contains two compartments 1a and 1b which are connected bya passage 1.

In the upper end of the casing in the compartment 1a is screwed a plug1d and in the upper end of the casing into compart- 1 ment 1b is screwedplug 1. These plugs are adapted to facilitate the placing of the severalparts in said compartments.

Tn the lower surface of compartment 1 is a valve seat 1f, and in thelower surface of compartment lb is a valve seat 1g, and adapt ed to fitthe valve seat lt is a packing 2a which is supported by a flange on thevalve 2. Fitting the valve seat'lg 1s a packing 3 which is supported bya flange on the valve 3. These valves are provided with guides 2b and 3badapted to facilitate their engagement with said valve seats.

Connecting with valve 2 is a valve stem `6, which extends out Jthroughthe plug 1d and is provided centrally and around said valve stem with astuiing box 8. Connecting with the valve 3 is a similar valve stem 7which extends in the opposite direction to valve stem 6, and is providedwith a similar stuiing box 9. Connecting with the valve 2 is acompression spring 1, which is adapted to close and to keep the valveclosed under certain conditions.

Tn connection with valve 3 is a compression spring 5 adapted to closeand to keep the valve 3 closed under certain conditions.

ln line with valve stem 7 and adapted to engage with the end thereof isa water pressure actuated valve stem 12a, so that when the waterpressure in valve 12 causes valve stem 12a to be pressed outward, itthrusts the valve stem 7 into said valve casing, thereby opening thevalve 3 by compressing the spring 5, thus allowing the gas to iiowthrough these compartments in accordance with the flow or amount ofwater pressure through valve 12.

. Connecting with valve stem 6 is a lever 6'cx which is pivotallymounted upon a support 11 at the point 11, and mounted on lever 6a is arod 6b which connects with a lever 10a, which is pivotally mounted onsupport 1l at the point 11b, and connecting with lever l0a is athermostat adjusting bolt 10b, which is attached to the extended end ofthe thermostat 10. This thermostat 10 is a single piece of pipe providedwith a plug 10c in its end and having an inlet l0d and an outlet 10e.This thermostat is rigidly attached to the support 11, at one end, andis supported by a guide 11C in which the thermostat is adapted tocontract and eirpand. The thermostat support 11 is shaped as shown inthefigure, and is provided with extended lugs 11d and 11", and is providedon one side with a bracket'lug llf, which is adapted for attaching it toa water heater. This support l1 rigidly connects these valves and thethermostat together, thus providing a positive action.

The operation of the thermostat valve 2 is as follows The heated waterenteringthe thermostat through the opening 10I will heat the thermostat,causing it to-elongate, which `in turn will relieve the leverl l0, whichwill relieve the lever 6, thus allowlng the valve stem 6 to be pressedinto the' casingby means of the compression sprlng 4, which closes thevalve 2. If however, the temperature of the water in the thermostat isnot too high, the contraction of the lthermostat will compress thespring 4, thus opening the valve 2..

It will be readily seen that with this construction, there is provided agood and stubstantial water heater regulator; that lthe supportconnecting the several parts together, provides a means of holding thedlfferent parts, rigidly, in their relative positions; that the doubleactuated valves provide a positive means of regulating the supply offuel to a water heater; that the single pipe thermostat construction, inconnection with the valves, provides avery simple operative means.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is 1. A water heater regulator comprising, agas valve casing divided into two separate compartments and providedwith an inlet and an outlet, a passage way connecting said compartments,a water pressure actuated gas valve, spring seated`on the pressure sidein v one of said compartments, a water pressure actuated valve foropening said gas valve and permitting the How of gas from onecompartment 1nto the other, a thermostat actuated valve normally seatedby a compression spring on the pressure side in the other compartment ofsald casing and adapted to control the flow of gas to a burner, a

',erated valve, and said support.

2. A water heater regulator comprising a supporting and connectingframe, provide with aI lug near itsmiddle, adapted to be rigidlyattached to aiwater heater, a thermostat consisting of an elongatedhollow casing, through which the heated water 'from the heaterl Hows',-rigidiy secured to said frame at one 'of its endsnear the -end of saidframe, a guide rigidly secured to said supporting frame near the middlein which the other end of said thermostat is shiftably mounted, a doublyactuated fuel supply valve rigidly secured to said support'- ing andconnecting frame, operative connections mounted o'n said frame betweensaid supply valve and said thermostat whereby the movement oi saidthermostat is enlarged to one of the actuating portions of 'said sup lyvalve, and a watel` pressure actuated valve for actuating the ot erportion of said gas valve rigidly secured to said supporting frame,whereby 'said thermostat, fuel supply valve, operative connections andwater pressure actuated valve are rigidly secured and connectedtogether. y

In testimony whereof, I have hereunto subscribed my naine in thepresence of two subscribing witnesses;
